Get_Stepper_Status - Scanlab RTC6 PCIe Board Installation And Operation Manual

Ctrl Command

get_stepper_status

Function Returns the following status information for both stepper motor output ports: the current
statuses of the stepper motor signals, the currently defined CLOCK pulse period, status
"Busy" and status "Init", and the current values of the internal position variables.
get_stepper_status( &Status1, &Pos1, &Status2, &Pos2 )

Comments • For programming the stepper motor signals, see
Motors", page
• If the SWITCH signal (limit switch signal) is set to (pin is LOW), no more CLOCK pulses
are generated.
• Status "Busy" indicates that a previously initiated (by stepper_abs, stepper_rel, etc.)
set-position movement has not yet completed.
• Status "Init" indicates that a previously initiated (by stepper_init) reference run has
not yet completed.
